I'd agree that we tend to frame things in a reductionist way, but I don't think that's peculiar to Western thought so much as it is endemic to humans and their limitations. Given limited resources of time and knowledge the vast majority of people either attempt to limit the scope of the problem domain or opt for satisficing behaviors to achieve "good enough" results. It is rare that when confronted with a problem that a person has the luxury of time, creativity, and/or attention to derive first principles. It is doubly difficult when examining systems because the failings of most systems are not immediately obvious but instead the result of unintended consequences or the complexity of multiple conflicting behaviors resulting in perverse incentives... and if at the creation of the original system such problems were not foreseen what guarantees that the replacement system does not create worse results? Most people are cautious in proceeding when they are facing unknown (or unknowable) obstacles.
